Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, and in particular to a steering angle of a lifting-assisting pulley for preventing a door and window sash from sinking. Background Art

[0002] At present, with the increase in office buildings, inward sliding window sashes are becoming more and more popular. This type of window sash brings many hidden dangers. The extra-high and extra-wide window sashes are too heavy. The window sashes with the hinge side as the axis will produce a turning moment under the action of their own gravity. The greater the center of gravity offset, the greater the turning moment, and the greater the friction and shear force on the hinges, which seriously affects the service life of the hinges; excessive sash weight and sash width will lead to inconsistent sash diagonals, and the rectangular sash will become a diamond-shaped sash, which is what we call sash corner drop. Mild cases will lead to poor sealing and air leakage; severe cases will lead to scratches on the frame and sash, poor switching, hardware locks that damage the sash profile, and even the inability to close or open the door and window sashes.
